Pull rod type air-drop box with wheel discs capable of being hidden

Abstract

According to the pull rod type air-drop box with the wheel disc capable of being hidden, the wheel disc and a wheel disc support can be hidden in a hidden area and are not prone to being damaged during air-drop, the pull rod wheel disc can be pulled up to be dragged and carried during use, and generally, multiple sections of the wheel disc of the air-drop box for air-drop are in a roller shape. A plurality of draw-bar boxes on the market can roll at will when not used due to the fact that the wheel discs can not be contracted and hidden, the wheel discs are always obstructive when the draw-bar boxes are placed on luggage racks of trains and passenger cars during traveling, and therefore the draw-bar box is not only suitable for air-drop boxes but also suitable for civil luggage boxes.
